What are the disadvantages of Amazon VPC
The disadvantages of AWS VPC are that it lacks scalability and high availability. AWS VPCs are great for hosting applications that require high levels of security and need to be tailored to specific needs. The disadvantage is that they are more expensive because you are essentially renting space on AWS servers.
What are the disadvantages of VPC peering
Disadvantages of VPC Peering
Limited support for on-premises networks: VPC Peering does not natively support connections to networks, requiring additional configurations or solutions like VPN connections or AWS Direct Connect.
What are the disadvantages of private clouds
Limitations of private cloudLimited scalability – The extent to which you can scale up in a private cloud is limited by the amount of infrastructure you have.Huge initial capital expenditure – With the private cloud you have to procure all the cloud infrastructure.
Which of the following is a disadvantage of the private cloud model
Public Cloud and Private Cloud: Disadvantages
Private Cloud can be costly to set up and maintain, requiring dedicated resources and infrastructure. It may also lack the scalability and flexibility of the Public Cloud.

What are the limitations of VPC endpoint
The limitations of VPC endpoints
The VPC endpoint and service must be in the same region. VPC endpoints support IPv4 traffic only. Endpoints can't be transferred from one VPC or service to another. S3 bucket policies can be used to control access to buckets from specific gateway endpoints or VPCs.
Why default VPC is not recommended
A default VPC is suitable for getting started quickly, however, when you deploy complex applications and use multi-tier architectures you may need to keep parts of your network private or customize the network model, therefore it is recommended to create a non-default VPC that suits your specific requirements.
What are 3 disadvantages of the cloud

What is the main risk of using a private cloud
One of the most serious risks in any cloud environment is data breaches, which can result from unauthorized access, theft, or leakage of sensitive information. Data breaches can damage your reputation, incur legal liabilities, and expose you to cyberattacks.
What is a major disadvantage of cloud services
Downtime is often cited as one of the biggest cloud computing disadvantages. Since cloud computing systems are internet-based, service outages are always an unfortunate possibility and can occur for any reason. The financial impact of service disruptions and outages is staggering.
What is a disadvantage of AWS
Disadvantages of AWS
Amazon Web Services may have some common cloud computing issues when you move to a cloud. For example, downtime, limited control, and backup protection. AWS sets default limits on resources which vary from region to region. These resources consist of images, volumes, and snapshots.
What is the main disadvantage of Fulfilment by Amazon FBA
Disadvantages of Amazon FBA
High storage costs, which remain the same regardless of sales.
How many IP addresses can a VPC have
Get to Know Reserved IPs
0.0/22. The VPC includes 1,024 total IP addresses. This is divided into four equal-sized subnets, each with a /24 CIDR range with 256 IP addresses. Out of each of those CIDR ranges, there are only 251 IP addresses that can be used because AWS reserves five.
What is the benefit of using a VPC over not using it
Scalability: Because a VPC is hosted by a public cloud provider, customers can add more computing resources on demand. Easy hybrid cloud deployment: It's relatively simple to connect a VPC to a public cloud or to on-premises infrastructure via the VPN. (Learn about hybrid clouds and their advantages.)
What is the difference between VPC and default VPC
The default VPC is a virtual network that is automatically created for the customer's AWS account when EC2 resources are provisioned for the first time. A non-default (also known as Customer VPC) is not created automatically when EC2 resources are provisioned, and the customer must create their own VPC.

|---|---|---|
| VPCs per Region | 5 | Yes |
| Subnets per VPC | 200 | Yes |
| IPv4 CIDR blocks per VPC | 5 | Yes (up to 50) |

Can a VPC have more than one Internet gateway
Each VPC can have only one Internet Gateway. Each Internet Gateway can be attached to only one VPC. If there is no Internet Gateway attached to a VPC, then the VPC will not have any connectivity with the Internet. This can be useful for 'internal' applications, such as Dev and Test.
Why we should not use default VPC in AWS
The default VPC in an AWS region is generally considered insecure and should be avoided. The default security groups, NACLs, and route tables are generic in nature and do not lock down sensitive ports or traffic routing.
